Summary:
862bf0f153 introduced a regression(sorry
for that): if you close a confirmation dialog(with the Scale effect and the
Dialog Parent effect being enabled), the main window(s) will flicker.
That flickering happens because the C++ version of the Scale effect and
AnimationEffect unref deleted windows in different places. AnimationEffect
unrefs deleted windows in prePaintScreen, which btw is not the best
place to do that. The C++ version unrefed windows in postPaintScreen.
So, when the Scale effect has finished animating the main windows, it
will unref them, but windowDeleted signal won't be emitted immediately.
Which means that the Dialog Parent won't be able to delete corresponding
animations on its side and main windows will be painted for a single
frame.
This change addresses flickering by adjusting prePaintWindow in
AnimationEffect so deleted windows won't be painted if none of
animations keeps them alive.
Test Plan:
(make sure that both the scale and the dialog parent effect are enabled)
* Go to System Settings > Application Style > Window Decorations;
* Select a decoration that is different from the current;
* Close the system settings window (don't click "Apply" button);
* When a dialog is shown, click "Discard" or "Apply" button.

When an action with a given id changes, the display names change for all
actions in that

The KCM sets the ID to "kwin" but does not explicitly set a display
name. This means it is automatically deduced which will be kcmshell or

Summary:
If you activate the Present Windows effect and then the Desktop Grid,
you'll be able to see the close button from PW. The reason for that is
PW doesn't destroy the close button and DG doesn't filter it out.
This patch addesses this problem by syncing DesktopGridEffect::isRelevantWithPresentWindows
with PresentWindowsEffect::isSelectableWindow.
On X11, the close button is filtered by the isSpecialWindow check. On
Wayland, the close button is filtered by the acceptsFocus check.
The proposed solution is kinda hack-ish, but on the other hand, we have
to keep those two methods in sync anyway.
In addition to the close button, notifications won't be displayed too.

Summary:
Now, when the scripting effects API has all required ingredients to port
the Scale effect to JavaScript we finally can do it.
The main rationale for porting this effect to JavaScript is that
scripted effects API lets us focus more on what we want instead of
"how".
Visually, the ported version doesn't deviate from the C++ version.
Test Plan:
* Enable the Scale effect;
* Open/close a window.

Summary:
When using the natural layout algorithm with the fill-gaps option, a small
error (less than one) is introduced in windows' aspect ratio each time they are
enlarged due to floating-point roundoff.
Currently, the algorithm computes the width and height enlargement factors and
then attempts to enlarge in each of the four possible directions, repeating
until it can't enlarge any windows any further. Hence, this aspect ratio error
can be multiplied by up to four. Especially for small, long, and narrow
windows, this can result in a total error of greater than one by the end of
that loop iteration. If this occurs, on subsequent iterations the height
enlargement factor might then be computed as negative violating some of the
core assumptions of the algorithm and resulting in the loop iterating endlessly
until one of the window dimensions overflows, freezing the program for up to
several minutes.
To fix this, the height enlargement factor should be re-computed based on the
new width each time the window is enlarged, ensuring the error introduced in
the aspect ratio never exceeds one.

The most reliable way to reproduce the freeze seems to be to activate the
desktop-grid effect while a tool-tip window is fading in.
Ensure desktop-grid is configured to use present windows, and that present
windows is configured to use the natural layout algorithm with the fill gaps
option selected.
The freeze is still intermittent, but using this method should be able to be
triggered within about 10 tries without this fix.
After applying the fix, the freeze has never been observed.

Summary:
There were several reasons to rewrite the Minimize Animation effect in
JavaScript: to simplify code and to get rid of full repaints. One could
say that nothing prevents us from calculating the dirty region in
postPaintScreen or postPaintWindow and it is correct, but with the
scripting effects API the dirty region will be calculated for us, so we
can focus more on "what we want" instead of "how".
Visually, the "old" effect and the rewritten one look quite the same.
Except one tiny bit: if a window doesn't have an icon in the task manager,
it won't be animated. The reason for that is the purpose of this effect is
to show where the window will be after it's minimized, if the window
doesn't have icon in the task manager, one can't click at the center of
the screen to unminimize the window.
There is one significant change, the name of the effect was changed to
"Squash". If we put this effect and the Magic lamp effect under "Window
Minimize Animation" category (or if we add some "heading" label), then
the old name and the name of the category would "conflict". The new name
was suggested by Nate Graham and it very closely describes what the
effect does. "Scale" doesn't fit this effect because while a window is
being animated, its aspect ratio is not preserved.
